Provenance
a place of origin; specifically, the area from which the constituent materials of a sedimentary rock or facies are derived (adapted from Ref (1)). 3.1.10.1 Discussion—In the context of forensic provenance analysis, geological material is analyzed and interpreted to estimate or limit the geographic or environmental conditions of the source of this material to provide an investigative lead. For example, soil on a shovel can be examined to aid in the search for a clandestine grave, typically by comparison of observa- tions to reference data. Geographic attribution is an alternative term for provenance.
